\ showing same secured to the ground and in engagement with a pipe;

Figure 2 is a top plan view of the machine of Figure 1 and showing the arrangement of the base, the carriage and a hydraulic piston carried by said base for moving said carriage with respect to said base, said base, carriage and hydraulic piston being elements of the machine;

Figure 3 is a transverse horizontal sectional view taken substantially upon the plane indicated by the section line 3-3 of Figure 4 and showing the construction of the pipe gripping means, a pipe being illustrated as being gripped by said means for pushing same; and

Figure 4 is an enlarged end elevational view of the machine of Figure l as viewed from the left and showing the arrangement of the various eiements of the machine.

Similar characters of reference designate similar or identical elements and portions throughout the specification and throughout the different views of the'drawings.

Referring now to the drawings in detail, the machine which is the subject of this invention includes a base referred to generally by the reference-numeral Ill. The base It includes a pair of spaced'parallel side members l2 each having base flange M, a narrow longitudinal side wall portion it normal to the base flange M, and an inwardly sloping upper side wall portion i8. EX- tending inwardly from the upper inwardly sloping side wall portion I8 is a flange 213 iii-spaced parallel relation to the base flange M. The base flange Hi and the flange 20 in combination with the side wall portions 16 and i8 form a guideway 22.

As is best shown in Figure l, the inwardly extending upper side wall portion i8 is provided with aconcave upper edge 2 5 and outwardly and downwardly sloping end edges 26; Rigidly secured to each side wall portion 18 adjacent its end edges 2% are downwardly and outwardly sloping tubular sleeve members 28 whose bottoms are coplanar with the bottom surface of the base flange l4. Removably carried by each of the tubular sleeve members 28 is a ground engaging stake 30 having a head 32 and a pointed end 34.

The spaced side portions l2 of the base ill are secured together in spaced parallel relation by transverse frame members 36 extending between the side wall portions 18 and secured thereto adjacent their end edges 26. The transverse frame members 38 are also secured to the upper surface of the flanges 20 adjacent their ends. The lower edge of the transverse frame member 36 between the flanges 29 is concaved upwardly.

Slidably mounted within the guideways 22 of the sides 42 is a generally channel shaped carriage 38 having a top horizontal plate portion 40, side flanges 32, and inturned wing flanges A l at the lower edges of the side edges 42. A top plate portion 46 engaging beneath the flanges 2t and the inturned wing flanges 44 overlying the base flanges l 3.

Referring now to Figure 3 in particular, it will be seen that the carriage 38 only extends a portion of the length of the base it and is provided at one side in the interior thereof with an elongated pipe gripping block 46 which is secured to the flanges 42 and 44 at one side of in spaced relation to the upper plate 45. The ner edge of the pipe gripping block 46 is provided with a longitudinally extending triangular groove 48 for receiving a portion of a longitudinally extending pipe therein.

Carried at the other side of the carriage 38 are a pair of spaced pipe gripping clamps 55 and 52. The pipe gripping clamps 56 and 52 are provided with handle portions 5i and 56, respectively, extending therethrough and journaled in the wing flange 4 and the upper plate 46 of one side of the carriage 38. As is best illustrated in Figure 4, mounted on the handles 54 and 56 between the upper surface of the pipe gripping clamps 59 and 52, respectively, and the plate portion are compression springs 58. The compression springs 58 tend to cause binding of the pipe gripping clamps 50 and 52 so that they are maintained in any position to which they are turned by the handles are provided with an offset crank portion at their upper ends in order to facilitate rotation of the handles and their associated pipe gripping clamps.

Referring now to Figure 3, it will be seen that the pipe gripping clamps 50 and 52 are each generally rectangular in plan view and each having a rounded side opposite its respective handle. The rounded side of each the pipe gripping clamps 56 and 52 is provided with a triangular notch similar to the triangular notch in the edge 48 of the pipe gripping block 46.

It will be noted that the rounded side of the pipe gripping clamp 50 is illustrated as being in engagement with the surface of a pipe 66 and clamping same against the edge d8 of the pipe gripping block 56. Any attempt of the pipe to move to the left, as viewed in Figure 3, will result in clockwise rotation of the pipe gripping clamp 56 about its handle 54, and thereby more tightly grip the pipe 66.

If it is desired to move the pipe 50 to the left, as illustrated in Figure 3, the pipe gripping clamp 50 is released from engagement with the pipe 60 by turning its handle 58, and the pipe gripping the carriage and 56, respectively. The handles 54 and 55 r clamp 52 is turned into engagement with the pipe 60. It will be noted that the shape of the pipe gripping clamp 52 is just the opposite of that of the pipe gripping clamp 56 so that when the rounded side of the pipe gripping clamp 52 engages the pipe 66, movement of the pipe 60 to the right, as viewed in Figure 3, will result in counterclockwise rotation of the pipe gripping clamp 52 to tightly clamp the pipe 60 against the pipe gripping block 46.

Referring now to Figure 2 in particular, it will be seen that secured to the inner side of the upper side wall portions 18 in transverse alignment with the tubular sleeve members 28 are pairs of aligned tubular support members 62. The tubular support members of each pair are in alignment with each other with their free ends spaced slightly from each other in opposed relation. The tubular support members 62 are additionally supported by being welded to the upper edge of their associated transverse frame member 36.

Carried within each pair of tubular frame members 62 is a rod 64. In order that the rod 64' may be inserted within and removed from the tubular support member 62, one side wall portion 18 and its associated tubular sleeve members 28 are provided with aligned apertures in alignment with the associated tubular support members 62. The aperture in the outer portion of the tubular sleeve members 28 being clearly shown in Figure 2 and referred to by reference numeral 66. It will be noted that the rods 64 can be removed from within the tubular support member 62 only by first removing the ground engaging stake 30 inserted within its associated tubular sleeve mei ber 28 having the aligned aperture 63 therein.

Pivotally secured on one of the rods 64 between the opposed ends of the tubular support members 62 is a hydraulic piston 63 having a cylinder 10 and a connecting rod 72. The cylinder 10 has on its rear end a connecting block '74 which is mounted on the rod 64. The free end of the connector rod 12 is pivotally connected between a pair of spaced parallel ears 76 secured to the upper side of the plate portion 40 of the carriage 38. The connection between the connector rod 72 and the ears (6 is a, pivotal connection due to the connection of the elements by a pivot pin 18.

Carried by the cylinder 70 is a pair of hydraulic hoses 80 and 82 which are connected to a hydraulic motor and a reservoir through a four way valve (not shown). The hydraulic piston 68 being a double acting piston, it is readily apparent that the connecting rod 12 may be 'reciprocated by selectively positioning the four way valve.

While the hydraulic piston 58 is illustrated as being connected to the rod 54 at the left side of the machine as viewed in Figure 2, it may equally well be secured to the rod 64 at the right side of the machine. Due to the fact that the hydraulic piston 63 may be connected to either end of the base 10, it is obvious that the pipe gripping clamps 56 and 52 may be utilized to both push and pull pipe 60 depending upon the position of the hydraulic piston 68.

While this machine has been illustrated and described as being secured to the ground for the purpose of moving a pipe 60 therethrough and pushing same into dirt, it is not intended to so limit the invention; the machine is capable of moving other rod like members through dirt, either by pulling or pushing, or it may be uti lized to pull pipe from wells. Furthermore, it may be utilized for pulling cables through conduits or other similar uses. 7

The operation of this machine will be readily understood from the foregoing description of the mechanical details thereof, taken in connection with the above recited objects and drawings. Further description would appear to be unnecessary.
